To all whom it may concern:

Be it known that I, HENRY DESBOROUGH PHILLIPS, of Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in (Zomposition of Matter for Concrete; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved composition of matter for concrete, the object of the invention being to provide a composition which when set w1ll be impervious to y. This compositimTi's'mad'e'up 'ifi'batches and consistsof the following ingredients, combined in substantially the following proportios, viz,-

The cement and chemicals are thoroughly min ledjn a dry state, after which the sand an grav or ro en stone are added. To the mixture thus formed sufiicient water is added and when thoroughly mixed the batch is ready for use.

The ingredients in the roportions set forth are particularly well ad apted for making concrete. In the composition described, the arsenious acid renders the concrete very tough and strong and the mica cr stals render it non-absorbent, which 111 concrete work avmg fully described my invention what I claim as new and desire to secure by Letters-Patent, is,

The herem described composition of matter for the manufacture of concrete, consistin of cement, arsenious acid, mica crystals, su fur, sand, and gravel or broken stone, in the proportions described.

In testimony whereof, I have signed this specification 1n the presence of two sub- SCIlblIlg wltnesses.
